7 Claims.

This invention relates to metallic doors and one I of the primary objects of the invention is to provide an improved construction which is inexpensive and simple to manufacture, of great strength and rigidity, and of pleasing appearance.

Other objects reside in the provision of improved features of construction hereinafter more specifically described.

How the foregoing, together with such other objects and advantages as may hereinafter appear or are incident to my invention are realized, is illustrated in preferred form in the accompanying drawings, wherein- Figure 1 is a front view of a door constructed in accordance with my invention;

Figure 2 is an enlarged vertical cross section through the door taken on the line 2-2 of Figure 1;

Figure 3 is an enlarged vertical cross section taken on the line 33 of Figure 1;

Figure 4 is an enlarged fragmentary plan view of the door;

Figures 5 and 6 are enlargedfragmentary plan sections taken on the lines 5-5 and 6--6 respectively of Figure l;

Figure 7 is a fragmentary perspective view of the upper portion of the door with certain parts omitted for the sake of clarity and other parts shown in position for insertion in place; and

Figure 8 is a more or less diagrammatic eleva tional view of welding apparatus employed in constructing the door.

Figure 9 is a fragmentary section taken on the line 9-9 of Figure 1, illustrating bevelled corners I contemplate employing at edges of the stiles, cross rail, and lower panel.

. The door comprises hollow end stiles 10, a hollow upper cross rail H, a hollow lower panel section i2, and a glass panel i3. The construction of the end stiles, cross rail, and lower panel section is such that their outside faces lie in the same plane. Filling material, such as asbestos board filler, may be inserted in the hollow interiors of these parts.

The end stiles l0 are of rectangular form in cross section, and are of one piece construction with the seam located at and constituting the bottom of a panel receiving groove M.

The meeting longitudinal edge portions of these stiles are inwardly bent as indicated at in Figures 4, 5, and 6, and then laterally bent toward each other in lapped relation, as indicated at IE, to form the longitudinal panel receiving groove M with the lapped joint constituting a flat bottom for the groove. This lappedjoint is welded as by means of spot welds spaced along the length thereof.

This welding is accomplished by means of the apparatus illustrated in Figure 8 and comprising 5 a fixed bottom contact I! on which the stile or member to be welded is placed, a top contact I8 fitting the groove [4 in the stile and movable into contact with the bottom of the groove, a current transmitting member l9 which is placed inside of the stile in a position to be in vertical alignment with the bottom and top contacts I! and la. The bottom of the member [9 is in contact with the end wall of the stile and the top thereof is in contact with the lapped joint of the groove i4. 1 This member I9 is carried by a fixed pipe within which a smaller pipe 2| leading to'the hollow interior of the member I9 is located. One

of these pipes is provided with a water inlet and the other with a water outlet for the purpose of 2 providing water cooling of the device.

The upper portions of the inside end walls of the stiles in are cut away, as indicated at 22 in Figs. 3, 5 and 7, to accommodate the end portions 23 of the upper cross rail II, it being noted that 2 inturned flange portions 24 remain at the cut away portions. The top rail is provided with grooves 25 adapted to receive the flanges 24.

This top rail ll comprises a pair of spaced side members 26 and an upper spacing and reinforcing 3 member 21 of channel form. The upper edge portions of the members 26 are rebent as indicated at 28 and then inturned to provide lateral flanges 29 which serve as seats for the channel member 21 which is detachably secured in place as by 3 means of screws 30. The lower edge portions of the members 26 are bent inwardly and then upwardly as indicated at 3| so as to provide a panel receiving opening or slot 32 in the lower face of the cross rail. It is to be noted that the constructions of the upper and lower edge portions just referred to do not extend for the full length of the members 26, but terminate at the grooves 25 above mentioned so that the remaining end portions 23 of these members are of flat plate-like -form.

The end portions 23 of the cross rail Ii enter the upper portions of the end stiles and lie flat against the side walls of the stiles, the cross rail and stiles being secured together as by means of spot welding the portions 23 to the side walls of 5 tions 23 of the cross rail and tothe inturned portions 28 of the side members 26, it being noted that the flanges are slightly offset at 34 to accommodate them to any.difference of thickness at these points. The flanges may also be notched for the reception of the inturned flange portions 23 of the stiles. The inner end portions of the channel irons 33 are slotted or bifurcated, as indi cated at 35, for a purpose hereinafter appearing. The detachable reinforcing member 21 extends from the inner end portion of one channel member 33 to the inner end portion of the other channel member 33 and therefore serves as a closure for the open top of the cross rail. In order to complete the closure, extending portions 21a are provided on the member 21 for covering the bifurcated end portions of the channel irons 33.

The hollow lower panel section i2 is closed at the top and ends and open at the bottom, side seams 36 being provided at the outwardly turned flanges 31 and a panel receiving groove, similar to that of the end stiles, being "provided in the top face of the section. The outwardly extending end flanges 31 are received by the grooves in the end stiles and the panel section is welded to the stiles as by means of spot welding, access being had through the open bottoms of the panel section and the end stiles.

These open bottoms are closed by means of a reinforcing closure or member 38. The member 38 is provided with grooves 39 in its side flanges adapted to receive the inturned extended portions 40 and H of the panel section and stiles. The member 38 is welded in place.

Reverting now to the top construction of the door, it is pointed out that with the detachable member 2! removed, the glass panel i3 may be inserted in place through the top cross rail because of the fact that the lateral flanges 29 are spaced apart and the panel receiving groove 32 is bottomless and because of the bifurcated construction 35 of the inner end portions of the reinforcing channel irons 33. After the glass has been inserted, the top member 21 is secured in place to close the top of the cross rail. It will thus be seen that the glass may be inserted after the door is completely constructed and that replacements may be readily made merely by removing the top member 27.

In Figure 9, I have illustrated bevelled corners 42 which I contemplate employing at edges of the stiles l0, panel l2, and top rail H.

What I claim is: I

1. In a sheet metal door the combination of hollow end stiles, a hollow upper cross rail extending into the interior of the end stiles com prising side members and an upper reinforcing member, said side members being rebent at their upper edges for that portion of their lengths which lies between the end stiles to provide seats for the reinforcing member, and said reinforcing member extending between the end stiles and also constituting a top closure for the cross rail, and reinforcing members for the joints between the stiles and cross rail secured to the stiles and to the adjacent rebent portions of the cross rail and alsoconstituting top closures for the end stiles.

2. In a sheet metal door the combination of hollow end stiles, a hollow upper cross rail extending into the interior of the end stiles with side wall portions contacting with sidewall portions of the end stiles, reinforcing members for the joints between the stiles and cross rail, and a detachable top closure for the hollow cross rail, and said joint reinforcing members also constituting top closures for the hollow end stiles.

3. In a sheet metal door the combination of hollow end stiles, a hollow upper cross rail connecting the end stiles, said rail having an open top and a panel receiving opening in its bottom, a detachable closure for said open top, and channel reinforcing members for the joints between the stiles and cross rail, the webs of said channel members being bifurcated adjacent their inner ends and said detachable closure having portions overlapping the bifurcated portions of said channel reinforcing members.

4. In a sheet metal door the combination of hollow end stiles, and a hollow upper cross rail connecting said end stiles comprising side members having elld portions extended into the end stiles and an upper channel reinforcing member detachably secured between the side members, said side members being rebent at their upper edges to provide seats for the channel member and being rebent at their lower edges to provide a panel receiving opening.
